My first attempt at testing the cycle plotting (911513) has used footpaths at km 3 and 11. I checked the OSM data for the footpath it used at km 3, it says Bicycles Unspecified. The cycle path (route 21), which it hasn't used, says Bicycles Yes. I was using the Cycle Map and Auto Plot by bike.

It's possible that OSM shows that bridleway on the map but that it is not explicity tagged as suitable for cycling. You can check this using the instructions in the link in my previous post to examine the tags on the bridelway you are trying to plot on. Or if you can give me an example I can have a look into it here.

Hi - it's possible that the path you want to plot on is not designated on the map database for cycling. If you are using the Paths map you can update the map to correct issues like this. We have some advice on how to to this in our post on Making Changes to the Paths Map.

If I plot a map with map type set to "paths" and tick the "auto plot by bike" checkbox - you can't plot routes along bridleways (UK paths that allow bikes). It forces your royte to use footpaths which biking is not allowed.
